Abstract
OBJECTIVE: The purpose of this study was to determine the prevalence and severity of dental fluorosis in Mexican adolescents.
MATERIALS AND METHODS: A cross-sectional epidemiological study was carried out in 1,024 adolescents 12 and 15-years-old residing in three naturally fluoridated locales at high altitudes above sea level (> 2,000 m or > 6,560 ft) in Tula de Allende, Hidalgo, Mexico. Participants had lived in those communities from birth to their sixth birthday. Both the Modified Dean Index and the Community Fluorosis Index were calculated.
RESULTS: The overall fluorosis prevalence was 83.8 percent. Fluorosis prevalence in El Llano (3.07 ppmF), San Marcos (1.38 ppmF), and Tula Centro (1.42 ppmF) was 94.7, 89.8, and 81.9 percent, respectively. Overall, the Community Fluorosis Index was 1.85. We observed a high prevalence of dental fluorosis–mostly very mild (35.9 percent), but also uncommonly severe (20.6 percent).
CONCLUSIONS: At least 8 out of 10 adolescents had some level of fluorosis, and such prevalence is considered to be a dental public health problem. A relationship between fluoride concentration in water in each community and fluorosis was observed. The high fluorosis prevalence and severity might possibly be associated with the high altitude of the communities.

Refinement Impairments of Verbal-Performance Intelligent Quotient in Children Exposed to Fluoride Produced by Coal Burning.
To explore the relationship between total intelligence quotient (IQ), verbal intelligence quotient (VIQ), performance intelligence quotient (PIQ), and fluoride exposure in children aged 8–12 years in coal-burning fluorosis area of Dafang County, Guizhou Province, China. The Wechsler Intelligence Scale for Children Revised in China (WISC-CR) was used to test the total

The aesthetic management of severe dental fluorosis in the young patient
The prevalence of dental fluorosis appears to be on the increase. Although in its mild form the condition is not considered to be of cosmetic significance, the more severe forms can cause great psychological distress to the affected individual. This article discusses the prevalence and mechanisms of dental fluorosis, and

Risk of enamel fluorosis associated with fluoride supplementation, infant formula, and fluoride dentifrice use.
Eight hundred fifty 11- to 14-year-old residents of nonfluoridated communities in Massachusetts and Connecticut, who were born between 1972 and 1975, were investigated in a case-control study of the possible association between enamel fluorosis and exposure to fluoride supplements, infant formula, and/or fluoride dentifrice. The effect of median household income,

Epidemiological, clinical, and biochemical study of endemic dental and skeletal fluorosis in Punjab
The incidence of dental fluorosis in 46,000 children in the Punjab was assessed and compared with the fluoride content of their water supplies. Ten villages were selected for more detailed studies of skeletal as well as dental fluorosis. Factors other than the fluoride content of the drinking water which were found to influence

Dental Fluorosis Impacts Dentin in Addition to Enamel
Dental fluorosis is a mineralization defect of tooth enamel marked by increased subsurface porosity. The enamel, however, is not the only component of teeth that is effected. As several studies have demonstrated, dental fluorosis can also impair the mineralization of dentin as well. As noted in one review: "The fact that

Diagnostic Criteria for Dental Fluorosis: The Thylstrup-Fejerskov (TF) Index
The traditional criteria (the "Dean Index") for diagnosing dental fluorosis was developed in the first half of the 20th century by H. Trendley Dean. While the Dean Index is still widely used in surveys of fluorosis -- including the CDC's national surveys of fluorosis in the United States -- dental

Mechanisms by Which Fluoride Causes Dental Fluorosis Remain Unknown
When it comes to how fluoride impacts human health, no tissue in the body has been studied more than the teeth. Yet, despite over 50 years of research, the mechanism by which fluoride causes dental fluorosis (a hypo-mineralization of the enamel that results in significant staining of the teeth) is not

Dental Fluorosis: The "Cosmetic" Factor
Any condition that can cause children to be embarrassed about their physical appearance can have significant consequences on their self-esteem and confidence. Researchers have repeatedly found that "physical appearance [is] the best predictor of self-esteem" in adolescents, (Harter 2000) and that facial attractiveness, particularly the appearance of one's teeth, is a

Dental Fluorosis Is a "Hypo-mineralization" of Enamel
Teeth with fluorosis have an increase in porosity in the subsurface enamel ("hypomineralization"). The increased porosity of enamel found in fluorosis is a result of a fluoride-induced impairment in the clearance of proteins (amelogenins) from the developing teeth. Despite over 50 years of research, the exact mechanism by which fluoride impairs amelogin
